If we are serious about improving our schools, we must give every four-year-old child the opportunity to attend a high-quality, full-day prekindergarten program. And we must do it now. After all, children have only one chance to go to preschool. In implementing this plan, we look forward to working with the City Council and administration to make sure that this program serves all preschoolers, including preschoolers with developmental delays or disabilities, English Language Learners, and preschoolers living in temporary housing or foster care, so that the children who need this program most can benefit from it.
